Integrated Manufacturing Direct from Foshan, China

DERCHI, operating under Guangdong Dejiyoupin Doors and Windows Co., Ltd., represents the pinnacle of modern architectural door and window production. Spanning an expansive 180,000 square meter industrial hub in Foshan, Guangdong, our facility seamlessly integrates precision profile extrusion, thermal break assembly, computerized multi-axis CNC machining, automated glass processing, and robotic fluorocarbon/powder coating lines.

For more than two and a half decades, our technical focus has centered on solving real-world construction challenges for international builders, commercial general contractors, and prestigious architectural studios across North America, Australia, the Philippines, and Western Europe. By eliminating middlemen and maintaining end-to-end quality control, DERCHI provides direct factory pricing paired with verifiable international engineering compliance.

Full Compliance & Codes

Certified to CE, ISO 9001, AS 2047 N6 cyclonic standards, and UL 10C positive pressure fire testing to ensure swift building authority plan approvals.

Free CAD & BIM Drafting

Our dedicated structural engineering division converts architectural schedules and rough opening elevations into production-ready CAD shop drawings free of charge.

Export Crate Engineering

Zero transit damage guarantee through five-tier packaging: anti-scratch film, EPE foam wrapping, corner bumpers, desiccants, and fumigated steel-banded plywood crates.

Bilingual Time-Zone Support

Our project management teams provide direct, real-time technical synchronization throughout North American EST and PST standard operational hours.

Metallurgical Whitepaper

Engineering Standards for Heavy-Duty Architectural Extrusions

A rigorous examination of primary aluminium billets, mechanical properties, thermal break barrier physics, and durability metrics for exterior building envelopes.

Alloy Purity & Mechanical Yield

We exclusively utilize certified prime primary 6063-T5 and 6061-T6 virgin aluminium billets, completely eliminating secondary scrap melts. Achieving tensile strengths > 215 MPa and yield strengths > 170 MPa, our structural door mullions support massive oversized glass dead loads without long-term hinge sagging or frame racking.

Standard: ASTM B221 / EN 755-2

Thermal Barrier Engineering

Condensation prevention and energy retention in extreme climates are resolved using Technoform PA66 GF25 (25% glass fiber reinforced polyamide) structural insulating strips. By segregating exterior and interior aluminium chambers, we break conductive pathways, achieving U-values low enough to satisfy strict IECC and Energy Star specifications.

Insulation: PA66GF25 Multi-Chamber

Surface Passivation & Coatings

Our automated horizontal and vertical coating lines utilize AkzoNobel and PPG fluorocarbon (PVDF) 3-coat finishes alongside architectural powder coating meeting Qualicoat Class 2 standards. Tested to withstand 4,000+ hours of continuous neutral salt spray without blistering, chalking, or delamination in harsh coastal salt-mist environments.

Technical Q&A

Procurement & Engineering Frequently Asked Questions

Essential guidance addressing technical specifications, lead times, logistics, and verification for foreign procurement specialists.

QWhat primary aluminium alloy specifications are utilized across door profiles?

We work predominantly with 6063-T5 for complex, tight-tolerance architectural extrusions and 6061-T6 for high-load structural pivot uprights and oversized commercial hinges. All billets conform strictly to ASTM B221 and GB/T 5237 chemical composition standards.

QHow does DERCHI verify thermal insulation and avoid thermal bridging?

We incorporate structural polyamide 66 with 25% glass fiber (PA66 GF25) thermal barrier strips manufactured by Technoform or equivalent tier-1 producers. Using double and triple chamber cavities, our systems achieve U-values as low as 0.8 to 1.4 W/(m²·K).

QCan you accommodate custom rough opening dimensions and imperial door schedules?

Yes. All OEM/ODM production is custom-manufactured. Our engineering division works directly from architectural schedules, converting fractional inch dimensions or metric measurements into shop drawings with complete threshold and flashing interface details.

QWhat testing certifications are available for North American building inspections?

Our systems hold CE, ISO 9001:2015, Australian AS 2047 cyclonic impact, and UL 10C positive pressure fire-rated certifications. Project-specific NFRC thermal performance certificates and structural calculation packages can be provided during submittals.

QWhat is the standard production lead time and ocean container crating protocol?

Standard OEM manufacturing cycles range between 25 to 35 business days following CAD shop drawing sign-off. Finished assemblies are sealed in moisture-barrier wrap, padded with high-density EPE foam, and encased in fully enclosed fumigated plywood crates.

QCan our team inspect the manufacturing plant before container dispatch?

We welcome third-party technical audits (such as SGS, TÜV, or Bureau Veritas) and offer live 360-degree interactive factory virtual tours. We also provide full factory acceptance testing (FAT) video documentation for each unique production order.
